How to get the NIC number and description by program

[alex.]

I may need to choose one of the NIC. Thanks.

Look under the "Data Communication >> Protocols >> TCP" palette and you'll find two VI's called "IP to String" and "String to IP". The combination of these will allow you to find all IP addresses or names of the network adapters on your computer. (Note: you can right click on String to IP and select "Multiple Outputs" which displays all available network adapters).

Coincidentally, this was one of the questions in the head-to-head Coding Challenge at NIWeek this year. 😉

If you need the description, you must make DLL calls into OS libraries.

The number of the NIC is the MAC adress, or the Physical Address. I have a trick to do that if your problem is not solved.

Coq Rogue is right... I didn't answer your question at all! Unfamiliar with the term "NIC number", I assumed IP rather than MAC address. A simple Google search on my part would have saved some embarrassment! 

OK, so to find a MAC address, the routines you use are dependent upon the OS of your target computer. Here are some links that give several methods for different targets:

Use the system exec to run an ipconfig command then parse the output.

Hi Coq Rouge,

May I know how you do it.

I need to get the info as below. The number 1, 2 and 3 with their description.

1. \Device\NPF_{..................} (Realtek RTL8168C/8111C PC
I-E Gigabit Ethernet NIC)
2...............

3...............
